The spy camera is an irreplaceable everyday helper to increase the security in your premises. Thanks to the motion detector feature, the camera only films when something really happens. Thus, it saves a lot of electricity and does not film empty rooms.

With our big spy camera test 2021 we want to help you find the perfect device for you. We have looked at different spy cameras and picked out the most important facts for you. We also show you the advantages and disadvantages of a spy camera.

The most important facts

  • Unlike a conventional camera, a spy camera is stationary. With the help of the motion detector feature, you can save a lot of power and storage space.
  • With integrated night vision, you can expect crisp images and videos of all events even at night.
  • Because it is so easy to use, a spy camera is also suitable for beginners. It can also be set up and operated from a mobile phone.

The Best Spy Camera: Our Picks

Buying and evaluation criteria for spy cameras

If you search for the perfect spy camera for you on the internet, you will come across a variety of models and offers. In the following, we will show you which aspects you can use to decide between these many possible spy cameras.

In summary, these are:

Battery life

The longest possible battery life is essential for a spy camera. Not only the pure continuous runtime is important, but also the standby mode, as long as nothing is happening.

In standby mode, most spy cameras can remain switched on for several months.

Some models can even last for several years.

The continuous runtime is several hours for most models. This is important, for example, in the event of break-ins and enables better analysis of the data.

The longer the battery life, the less criminal activity is missed.

Memory size

The memory size is very important so that more image and video material can be recorded. Due to the high image and video quality of spy cameras, the data requires a huge amount of memory.

The larger the capacity of the memory chip, the more and longer can be filmed.

Type Capacity
Micro SD 64 Gigabyte
Micro SD A1 128 Gigabyte
Micro SD Ultra 400 Gigabyte

Depending on the target, each memory chip has its advantages and disadvantages. Smaller ones usually don't last long, but the exact picture and video material is easier to find. The danger with a small one is that it cannot document everything because of its low capacity, so important moments can be missed.

Memory chips with a large capacity last for a long time. So there is usually no danger of missing an important moment. On the other hand, it is often difficult to find the correct picture and video material.

Picture quality / video quality

The image and video quality is essential for the evaluation of the data.

The better the image and video quality, the easier the subsequent evaluation.

Image quality is much better than video quality. This is because an image only has to focus once and video recordings have to do this all the time.

In addition, the frame rate for videos is important for the video quality. The more frames per second (fps) a spy camera has, the more effective it is. Most spy cameras have a resolution of 30 frames per second, while some manage just 10 frames per second.

Field of view of the viewing angle

Having the widest possible field of view of the viewing angle is always essential so that you don't miss anything. It also helps to film several events in a room at once.

All models have a viewing angle of at least 120 degrees. The top models even manage a viewing angle of up to 360 degrees.

Some models even have a swivelling head and a tiltable camera housing that can be digitally adjusted. You can preset it to move from side to side at a certain interval. However, with this default setting, you miss many important moments. For this reason, the spy camera should have a swivelling head that can follow every movement.

Size / Depth / Dimensions

Spy cameras come in many different sizes and variations.

The large models are about 15 centimetres high, 12 centimetres wide and 10 centimetres deep. The small models, on the other hand, are just two centimetres high, two centimetres wide and one centimetre deep. These models are mostly intended for office spaces.

Some spy cameras can be bought already integrated into objects. On the one hand, spy cameras can be bought integrated into furniture, which is ideal for companies. On the other hand, spy cameras are also integrated into objects such as fire alarms, which is feasible in all buildings. There are also spy cameras that can be bought integrated into picture frames, which is ideal for families.

Guide: Questions you should ask yourself before buying a spy camera

Before buying a spy camera, there are a number of factors you should consider. In the following sections, we have summarised and detailed some of these factors for you.

What is special about a spy camera and what advantages does it offer?

With a spy camera, you can easily have your house monitored without much effort. Due to its small size, it can be hidden in any room and is not visible to outsiders.

With a spy camera, you can capture crisp, clear images and video of everything that happens when you're not at home.

Thanks to an integrated motion detector, the camera only records when it detects movement. Otherwise, the spy camera is in stand-by mode and does not consume too much power.

In addition, there is the possibility that an infrared night vision function can either be purchased or is already integrated. With the help of this night vision function, the spy camera can take razor-sharp pictures even in absolute darkness.

What types of spy camera are there?

In the following, we would like to introduce you to the different types of spy cameras. There are two different types, both of which have advantages and disadvantages.

Classic spy camera without features

One type of spy camera is the variant without features. This device has neither night vision nor a motion detector built in. However, you can control it with your mobile phone and always keep an overview through live images.

  • Controllable by mobile phone
  • available everywhere
  • cheap
  • easy to use
  • no motion detection
  • pictures and videos at night impossible
  • needs a lot of power
  • needs a lot of unnecessary storage space

Spy camera with features

Another type of spy camera is the variant with features. A motion detector is always integrated in these models. More expensive models often even have an integrated infrared night vision camera. This means that crisp images and videos can be taken even at night.

Unlike the integrated night vision function, the spy with motion detector and the night vision device can both be replaced inexpensively and without problems in the event of technical problems.

  • Sharp images and videos in the dark
  • Saves power and storage space in stand-by mode
  • Controllable by mobile phone
  • More expensive
  • Not suitable for beginners
  • More complicated to use

Who is a spy camera suitable for?

A spy camera is just the right thing for you if you want to increase the security of your premises. With a spy camera, you can leave the house without worrying.

By purchasing the additional motion detector, the camera only documents all activities in the event of movement. If nothing happens, it remains in stand-by mode and does not consume unnecessary power. With the help of a night vision add-on, you don't have to worry about leaving the house at night.

So, if you want to increase the security of your premises and worry less about your valuables, a spy camera is just what you need. A spy camera is also a real added value for offices and families.

How much does a spy camera cost?

The price range for spy cameras is wide. Depending on the model, variation and manufacturer, the price is often an indicator of the image and video quality as well as useful add-ons. The cost of a spy camera starts at €15 and can rise to over €500 depending on the variation.

The need for accessories depends strongly on the purpose of the camera.

Price range accessories
15-29 euros usually none included
30-79 euros memory chip included
More than 80 euros memory chip and night vision included

A spy camera in the price category from €15 is a suitable entry-level model. Here you will usually find only the basic functions of a spy camera without any additional features. You should not expect a master camera with very good picture and video quality in this price category.

The higher the price of a spy camera, the more quality and features you can expect.

The material of the housing of a spy camera is made of plastic in the cheaper models; metal is rarely used.

Unlike the cheaper models, the more expensive spy cameras are mostly made with light metals. In addition, the more expensive models tend to be waterproof and even have a rotating head.

The more a spy camera costs, the better the image and video quality.

How big is a spy camera usually?

A good spy camera will significantly increase the security of your home and premises. It can be placed in any room without any problems and usually doesn't take up too much space. Some are even so small and camouflaged that they are barely visible to the naked eye.

The size depends greatly on the model, the manufacturer and the purpose. An average model has a width of 5 centimetres, a depth of 2 centimetres and a height of 6 centimetres.

Is there also a waterproof spy camera?

Yes, there is. However, the cheaper models start in the middle price segment for spy cameras, i.e. at around 100€. This makes them more expensive.

A waterproof camera is recommended for outdoor use.

The problem with outdoor spy cameras is that they are easily identified by outsiders. In addition, when used outdoors, neither the neighbour's property nor public land may be visible on it. By law, you are only allowed to film your own property.

In the case of companies, there are even more restrictions. There, filming is only allowed if all parties involved are informed in advance and give their consent. In addition, there must be concrete suspicion when monitoring individuals, otherwise the camera is liable to prosecution. Furthermore, there must be concrete interests that can only be preserved with video surveillance.

However, if it is only intended for the inner rooms, then you do not need a waterproof spy camera. You can get numerous cheaper models for this purpose.
